As you might know, texturing an object is a very time consuming process ! It includes the UV mapping process and the 2D texture creation in itself. Unfortunately, UV2UV will NOT do all this job for you...
...BUT it will be very helpfull if you need to rearrange UV coordinates of your object AFTER you have spent hours creating your 2D texture.
With the help of UV2UV you won't have draw it again, keeping all the benefits of your previous 2D artwork !
And this will be done in no time... (from a few seconds to several minutes depending on the size of your bitmap texture).
